What are the steps of converting a metric amount from one prefix to another?

Question

This is for my metric measurement practice homework, I have no idea what it means. Can anyone help? And does anyone know of some websites I can go to learn how to do this?

Answer 1

K H D M D C M thats, kilo, hecto, deka, meters, deci, centi, and mili.

If you move from left to right, you multiply by ten for every step you jump.

If you move from right to left, you divide by ten for every step you jump.

1 kilo = 1000 meters because you jump 3 spots, that's 10 * 10 * 10

Answer 2

To remember the prefixes of the metric units I learned the sentence:
King Henry Died Mary/Liz/Guenevere didn't care much.
King = Kilo = 1,000 or 10^3
Henry = Hecto = 100 or 10^2
Died = Deca = 10
Mary = meter/Liz = litre/Guenevere = gram
didn't = deci or 1/10 or 0.1
care = centi = 1/100 or 0.01
much = milli = 1/1000 or .001

To go from one prefix to any other just write out the letters like a previous answerer stated [using the appropriate name for the unit like Mary for meter]:
K H D M/L/G D C M
put the decimal after the letter representing whatever unit you have and then count how many times and in which direction you move it to get to the units you want. Ex: going from didn't/deci to much/mill is two to the right. Now take your number and move the decimal the same number of times in the same direction Ex: 1.870 decimeters [two to the right] is then 187.0 millimeters.

Answer 3

Lbs.intoounces

Answer 4

most are multiples of 10, 100, or 1000

Answer 5

you just have to multiply or divide that amount by 10,100,1000,etc. it'll be very useful if you have a table for converting.
